Feeding barnacles and some vent shrimp seen at Kawio Barat.

4651

Feeding barnacles and some vent shrimp seen at Kawio Barat. The tentacles, or cirri, of the barnacles, extend like blooming flowers, then fold back into the shell. The white fluff on the cirri are filaments of bacteria that grow in the passing vent water. The barnacles hold them out to promote growth, and then, apparently, retract the cirri to "lick their fingers."

Barnacles attached to hydrothermal vent spires feeding at Kawio Barat. Curiously , the density of barnacles decreases with height and at a color change on the large vent spire in the right center of the image.

Vent shrimp, one covered with what might be yellow bacterial material.

Closeup of pinkish red shrimp in vicinity of vent site.

4662

Shrimp covered with yellowish orange bacterial material.

4663

Vent shrimp - one covered with yellow-orange bacterial material and other covered with white material.

4664

Vent shrimp with varying degrees of coloration from either bacterial or mineral material. The seeming large shrimp is an optical illusion as it is swimming and closer to the camera than the shrimp on the rock face.

4665

Hydrothermal vent spewing heated fluids on the flank of Kawio Barat volcano. Rivulets of yellow and gray native sulfur are frozen in place after having run partially down the volcano's side. Numerous large shrimp can be seen below the vent.

Vent shrimp on frozen rivulets of gray and yellow sulfur.

4667

Vent shrimp on frozen rivulets of gray and yellow sulfur.

4668

Vent shrimp, gray rivulets of native sulfur, and some balls of yellow sulfur seen on volcanic gravel-like material in lower left.

2010 July 29

4669

Vent shrimp next to active vents. The center vent seems to be impregnated with sulfur giving it a yellow hue. Yellow material seen in some rivulets and in block in upper right is native sulfur.

2010 July 29

4670

Stalked barnacles, three scaleworms, and numerous vent shrimp are seen on a rock wall in the vicinity of a hydrothermal vent. The third scaleworm is well- hidden. Can you find it?

4671

Vent chimneys covered with stalked barnacles on the slopes of Kawio Barat.

2010 July 29

4672

An eelpout in the vicinity of hydrothermal venting activity. The rocks here bear evidence of past venting with iron oxide staining from hydrothermal fluids.

2010 July 29

4673

A pinkish red shrimp swims over rock with hydrothermal alteration as well as a carpet of yellow balls of native sulfur to left and bottom right. The yellow sulfur balls seem to grade into orange in the upper portion of the image, perhaps indicating additional interaction with iron oxide and sulfur.

Clams were sparsely scattered over the sediment near the vent fields of Kawio Barat.

4677

Barnacles with cirri extended, large chiton, and shrimp on vent structure at Kawio Barat.

Small white shrimp relatively devoid of coating, a large red shrimp with a coating of material (bacteria? mineral?) at a site where native sulphur has been deposited. Yellow sulphur indicates relatively lower temperatures when molten than black sulphur.

4687

Hydrothermal vents on Kawio Barat submarine volcano spew white smoke. Image captured more than 1,850 meters deep the Little Hercules ROV. Small lineal objects are shrimp. Yellow and black sulphur deposits are seen as well, yellow indicating a lower temperature while molten than the black.

Hydrothermal vent spires at Kawio Barat.

4689

Iron oxide stained hydrothermal vent spires with large orange shrimp

4690

Active vent spire and active vent in lower middle left where shimmering water is seen. Large field of barnacles is seen behind.

2010 August 3

4691

Large red shrimp at the edge of a field of barnacle on Kawio Barat. The red dots are laser lights used for measurement and are 10 cm apart. Thus the shrimp is a very large 20 cm or so shrimp.

2010 August 3

4692

A large red sea anemone -One of very few sea anemones at the Kawio Barat vent field. Barnacles with cirri extended and shrimp are also seen.
